# Sabrent Rocket 4 Plus 500GB — PCIe 4.0 TLC NVMe SSD (2026)

The Sabrent Rocket 4 Plus 500 GB is the entry point of Sabrent's enthusiast TLC PCIe 4.0 lineup — a Phison E18 controller with Micron 96L TLC NAND, but with reduced write speeds and endurance at this smallest capacity.

Quick answer: The Sabrent Rocket 4 Plus 500 GB is a fast boot drive for builders who want TLC NAND, DRAM cache, and PCIe 4.0 bandwidth without paying for capacity they do not need. Its 7,100 MB/s reads match the larger capacities, and 400 TBW is generous for an OS disk. The trade-off is reduced write speed — 5,500 MB/s versus 6,600+ on the 1 TB — and limited storage space. If you need a single drive for both OS and a game library, the 1 TB model is the better investment. If you already have bulk storage and just need a fast system drive, the 500 GB gets the job done without waste.

## Performance

Sabrent rates the Rocket 4 Plus 500 GB at up to 7,100 MB/s sequential reads and 5,500 MB/s sequential writes, with up to 500K random read and 500K random write IOPS. These read numbers push close to the practical PCIe 4.0 x4 bandwidth ceiling, but the write speeds are the lowest in the series — the 1 TB model is rated for 6,600 MB/s writes and the 2 TB hits 7,000 MB/s.

The Phison E18 controller brings improved sustained write handling compared to the older E16. The pseudo-SLC cache on the 500 GB model absorbs moderate bursts before writes drop to native TLC speeds, which typically sustain around 800–1,200 MB/s — substantially better than QLC alternatives. For an OS boot drive with application launches, game loads, and typical desktop workloads, the Rocket 4 Plus 500 GB behaves identically to its larger siblings on read-heavy tasks. For an OS boot drive handling primarily read operations and application launches, the Rocket 4 Plus 500 GB delivers an experience that is indistinguishable from its larger capacity siblings.

## Endurance, TBW & Warranty

The Sabrent Rocket 4 Plus 500 GB is rated at 400 TBW endurance, with a five-year warranty that requires product registration within 90 days of purchase — otherwise the warranty defaults to one year. At 400 TBW, writing 219 GB per day for five years would exhaust the rated endurance, far exceeding what an OS boot drive typically writes. The drive supports S.M.A.R.T. health reporting for monitoring remaining endurance. Sabrent handles warranty claims through their support portal, and the drive ships with a license for Acronis True Image for drive cloning. The drive supports S.M.A.R.T. health reporting for monitoring remaining endurance over time.

## Pros and Cons

**Pros:**

- 7,100 MB/s sequential reads near PCIe 4.0 ceiling
- Micron 96L TLC NAND for sustained write performance
- SK Hynix DDR4 DRAM cache
- Phison E18 12 nm controller with NVMe 1.4
- 5-year warranty with registration
- 400 TBW endurance adequate for boot drive use
**Cons:**

- Only 5,500 MB/s writes — lowest in the Plus lineup
- 500K random IOPS lower than 1 TB and 2 TB variants
- 500 GB limits use to OS and select applications
- Warranty drops to 1 year without registration


## Verdict

The Sabrent Rocket 4 Plus 500 GB is a fast boot drive for builders who want TLC NAND, DRAM cache, and PCIe 4.0 bandwidth without paying for capacity they do not need. Its 7,100 MB/s reads match the larger capacities, and 400 TBW is generous for an OS disk. The trade-off is reduced write speed — 5,500 MB/s versus 6,600+ on the 1 TB — and limited storage space. If you need a single drive for both OS and a game library, the 1 TB model is the better investment. If you already have bulk storage and just need a fast system drive, the 500 GB gets the job done without waste.

## Frequently Asked Questions

### Is the Sabrent Rocket 4 Plus 500GB good for gaming?

As a boot or game-install drive with limited capacity, yes. The 7,100 MB/s read speed and 500K random read IOPS handle game loads with no bottleneck. The constraint is storage: modern AAA titles range from 50–150 GB, so a 500 GB drive holds approximately 3–6 large games after accounting for OS and application space. For a gaming-only drive in a system with separate OS storage, it works well. As a single drive for everything, 500 GB is too tight for most gamers.

### Is the Sabrent Rocket 4 Plus 500GB compatible with the PS5?

It meets Sony's requirements. The PS5 requires a PCIe 4.0 NVMe M.2 2280 SSD with at least 5,500 MB/s recommended read speed, and the Rocket 4 Plus 500 GB delivers 7,100 MB/s — well above that threshold. The bare drive (without heatsink) fits within Sony's dimensional limits (maximum 110 x 25 x 11.25 mm with heatsink). Note that Sabrent sells the drive with and without a heatsink; for PS5 use, either verify the heatsink variant fits or use the bare drive with a PS5-compatible heatsink.

### Does the Sabrent Rocket 4 Plus have DRAM?

Yes. The Rocket 4 Plus uses SK Hynix DDR4 DRAM for the flash translation layer mapping table. Unlike DRAM-less drives that rely on the host system's RAM through HMB (Host Memory Buffer), the Sabrent has dedicated DRAM on the drive itself. This ensures consistent random-access performance regardless of system RAM pressure, which is particularly beneficial for workloads with heavy random I/O patterns.

### What is the TBW endurance of the Sabrent Rocket 4 Plus 500GB?

The rated endurance is 400 TBW (terabytes written), covered by Sabrent's five-year warranty with product registration. This works out to approximately 219 GB of writes per day over five years. For a 500 GB boot drive that primarily performs reads (OS and application loading), the actual daily writes are typically under 20 GB, giving you roughly 10x the headroom you need. The endurance is more than adequate for the intended use case.

### Is the 500GB slower than the 1TB Rocket 4 Plus?

Yes, on writes and random IOPS. The 500 GB model is rated at 5,500 MB/s writes and 500K random IOPS, while the 1 TB reaches 6,600 MB/s writes and 1,000K+ random IOPS. Read speeds are similar at 7,100 MB/s across both capacities. The performance gap comes from fewer NAND die on the 500 GB model, which gives the controller less parallelism to exploit during write operations. For read-heavy workloads (booting, game loading), the difference is imperceptible.

### Does the Sabrent Rocket 4 Plus need a heatsink?

The Phison E18 controller and Micron TLC NAND generate meaningful heat under sustained load, and temperatures can exceed 70 degrees Celsius without cooling. Sabrent offers the Rocket 4 Plus in both bare-drive and heatsink variants. If your motherboard has an integrated M.2 heatsink, the bare drive is sufficient. If not, the heatsink variant or a third-party M.2 cooler is recommended to prevent thermal throttling during sustained writes.
